Having seen the Green version I didn't think I would care for a BW conversion, but this is very elegant.
The lines and forms and composition really speak in the B&W version.
The question of colour or black and white for an image like this reminds me of a similar quandary I had with photos I took a few years ago in the rain forest on Vancouver Island. At the time, I was captivated by the lush greens, but when I processed the images, the greens seemed overwhelming. Eventually I converted the best to black and white and find that I prefer them.
Not an easy choice, but a fine image either way.

P.S. I misspelled "color" just to keep you happy, Jeremy.
